I created a principal GoGroup with others Internal GoGroups objects into principal GoGroup, and inside internal, exists for example GoGrid, GoText…
And just principal GoGroup has : this.Selectable = true and this.Deletable= true
And I would like to know if there is a event to get when user delete my internal GoGroup, … User will click in delete key to delete GoGroup object… and principal GoGroup should change size. See my Image:
